In the course of a careful revision of the arrangement and cata¬ 
loguing of the journals as now placed in the stacks, fifty numbers, 
nearly all unimportant, could not be found. Some of these may be 
misplaced, although a careful search has been made for them, and 
others may be returned. These were not reported in 1904 when the 
last account of stock was taken, because of the lack of a shelf-list of 
the section of Journals and Periodicals, so that the loss extends over 
an undetermined number of years. Since that account was taken 
two works, then reported missing, have been returned, but sixteen 
others cannot be found. It may be that some of these have been 
illegally borrowed and will be also brought back, but it is much to be 
feared that a volume of the Pennsylvania Geological Survey Reports, 
Catlin’s Indians, edition of 1841, Jardine’s Wilson’s Ornithology, 
Wolle’s Diatoms, Gurney’s Distillation (of which the title-card was 
also stolen from the catalogue) and Chavasse’s Advice to a Wife have 
been taken by the most detestably mean of all thieves, the one who 
appropriates for his own use what is being held for the general good. 
It is believed that these losses were all incurred before the arrange¬ 
ment of the library in the stacks. 
The Librarian attended the International Conference of Archivists 
and Librarians in Bruxelles, August 28-31. The proceedings were 
not of much importance to the Academy, but the brief visit to Belgium, 
especially to the towns between Antwerp and Bruxelles, was full of 
delight and profit. 
It gives the Librarian much pleasure to again acknowledge his 
indebtedness to his Assistant. William J. Fox, who, by his co-operation 
in the work of the Publication Committee, as well as of the Library, 
has afforded the opportunity for progress with the proposed detailed 
history of the Academy. 
Efficient service has also been rendered by Furman Sheppard Wilde, 
who has been an assistant in the library since last February.

Librarian.
